Oil ship

A technology of oil tanker and oil bag, which is applied to the tanker. It can solve problems such as low economic benefits, increased opportunities for crude oil to enter the sea, and marine environmental pollution, so as to achieve the effects of increasing economic benefits, improving operating rates, and reducing pollution.

Problems solved by technology

[0002] The existing oil tankers are basically empty one-way transportation. The distance from China to the Middle East is more than 4,300 kilometers. The oil price is 3,500 yuan / ton, and the cost of an empty oil discharge is 3,500×50×15=2,625,000 yuan; according to China’s annual import of 125 million tons of crude oil, the average distribution of the Middle East with 200,000 tons of oil tankers as the standard, a total of 63 oil tankers are needed each year, one-way The total cost of transportation is 63×2625000=1.64 billion yuan, that is, there is a waste of 1.64 billion yuan in the cost of emptying oil every year; in addition, seawater must be pressed into the cargo oil tank on the way back after the cargo oil is emptied to ensure the necessary draft and On the balance, crude oil needs to be used to wash tanks for reloading. On the one hand, it increases the cost, and on the other hand, it also increases the chance of crude oil entering the sea, causing pollution to the marine environment.
In order to solve the existing problems, double-hull oil tankers have been developed, and special ballast water tanks have been opened in the space between the double-hulls, which has solved the problem of marine environment pollution, but it still cannot be solved. The problem of transportation cost caused by one-way empty discharge
[0003] In the Chinese invention patent specification CN02122755.1 issued on July 12, 2006, a method for using the hull structure of a tanker for transporting oil and fresh water is disclosed. The tanks are all used as fresh water tanks. In addition, two dual-purpose tanks for ballast seawater tanks and fresh water cargo tanks are set in the center of the hull, which can transport oil cargo on the outbound journey and transport fresh water on the return journey. However, this method only changes the original ballast tank into a fresh water tank, and the space of the cargo oil tank is not used during the return journey, and the available space of the fresh water tank is relatively small, resulting in little economic benefit, and This structure is only suitable for tankers with double hulls, and the application range is not wide

Embodiment 1

[0011] Embodiment 1: As shown in the figure, an oil tanker includes a double-layer hull 1 and a cargo oil tank 2. An oil bag 3 and a water bag 4 are arranged in the cargo oil tank 2, and an oil pipe 31 is arranged on the oil bag 3. The bladder 4 is provided with a water pipe 41, the bulkhead 21 of the cargo oil tank 2 is provided with a slide rail 5, and a plurality of pulley assemblies 6 are arranged on the slide rail 5, and the lower ends of the pulley assemblies 6 are respectively fixed to the oil bladder 3 and the water bladder 4 connected, so as to realize the free contraction and alternate use of the oil bag 3 and the water bag 4, the wall of the oil bag 3 is provided with an electric heating device (not shown in the figure), and the outside of the oil bag 3 is provided with a steel wire mesh (Fig. not shown), the temperature resistance of the oil bladder 3 is greater than or equal to 80°C, and the pressure resistance is greater than or equal to 10 atmospheres. In additio...

Embodiment 2

[0012] Embodiment two: the tanker is a single-layer hull, and one to two double water bladders used as fresh water and seawater are used in all water bladders, so that when the tanker unloads oil and fills water or needs ballast between unloading and loading oil, Seawater can be loaded into the dual-purpose water bladder to be used as a ballast tank, and when arriving at an oil loading place or a water loading place, seawater can be released, or fresh water can be loaded, or space can be made for the oil bladder.

Abstract

The invention relates to an oil chip, which comprises shell and several oil chambers. The invention is characterized in that: the oil chamber has water cell and oil cell; the oil cell is arranged with oil tube; the water cell is arranged with water tube; the oil chamber has mover to alternatively select water cell and oil cell. The invention is based on present single-dual shell oil ship, to reduce cost. And since the oil cell and water cell are soft, it can buffer the impact of accidence. The oil cell can be used repeatedly without washing chamber, to reduce pollution. And the mover can fully use space, to improve economic benefits.

Description

technical field [0001] The invention relates to a transport ship, in particular to an oil tanker. Background technique [0002] The existing oil tankers are basically empty one-way transportation.
